[Boban calendar wheel]

by unknown

Published 1545

Ms. manuscript in the form of a circular sheet calendar

This Aztec pictorial calendar wheel, commonly known as the Boban calendar wheel, is printed on amatl (fig bark) paper. Initially dated to approximately 1530 by Doutrelaine, 1538 by John B. Glass and Donald Robertson in the Handbook of Middle American Indians, it has now been more accurately dated to 1545 or 1546. The initial dating of 1530 derives from the identification of two figures shown in the document: one in the upper left is said to be Hernán Cortés and the upper right figure is said to be don Antonio Pimentel, depicted as the son of Ixtilxochitl. Patricia Lopes Don argues for the compilation date of 1545-1546 based on the fact that don Antonio Pimentel Tlahuitoltzin was the ruler of Texoco de Mora from 1540-1546. The additional suggested date of 1538 can be traced to the Nahuatl notation of the year 7 Rabbit in the upper right hand corner but it still prior to Pimentel's rule

The outside ring of the calendar is comprised of glyphs for the eighteen months of twenty days, or veintenas, which make up the Aztec calendar. This outside ring surrounds a central three part history with three pairs of figures and glosses in Nahuatl and Spanish. The Boban calendar wheel is the result of a succession dispute following the Inquisitions burning of don Carlos Ometochtli and in which don Antonio Pimentel Tlahuitoltzin, seated above right, asserts his legal right to be ruler of Texcoco de Mora, with the support of don Hernando de Chávez, the figure on the upper left

The outside ring of the calendar as well as the central three part history is hand colored and probably drawn and composed by two hands. A reconstructed life size black and white photostat is included in the JCB bibliographical file
